“In support of the Pope’s urgent call to action, pro-environment group Americans United for Change is launching a new ad campaign in Iowa and New Hampshire calling on GOP candidates for president, including Jeb Bush, Marco Rubio, Bobby Jindal, and Rick Santorum, to stand with the pope over the oil billionaire Koch brothers that have spent millions of dollars trying to discredit climate science to protect their bottom line,” the group said in a statement released to WMUR.com Sunday night.

The group’s television ad, which will begin airing on Wednesday, can be viewed here. Its radio ad, which is being released on Tuesday, can be heard here.

AUC says the ad campaign is being launched in first-caucus state Iowa as well as in New Hampshire.
